Privacy Policy

Last Updated: March 10, 2026

Miriel AI is developed and operated by Poseidon R&D Inc (mirielai.com). This Privacy Policy explains how we collect, use, and protect your information when you use the Miriel app.

1. Information We Collect

We collect the following information to provide personalized nutrition guidance:

  • Child Profile Data: Name, birth date, gender, allergies, medical conditions, and dietary preferences
  • Health Information: BMI records, meal logs, and nutrition tracking data
  • Usage Data: App interactions, chat history with AI coach, and scan history
  • Device Information: Device type and OS version for app optimization
  • Anonymous Analytics: App usage events (e.g., features used, session duration) sent to our backend with a random device identifier — no personal information is included

2. How We Use Your Data

Your data is used to:

  • Generate personalized meal plans based on your child's profile
  • Provide AI-powered nutrition advice through our chat feature
  • Analyze food labels for allergen detection
  • Track nutritional intake and progress over time
  • Send optional notification reminders
  • Improve app quality through anonymous analytics (opt-out available in Privacy Settings)

3. AI Processing & Third-Party Services

This app uses the following third-party services:

Google Gemini AI

  • Purpose: Nutrition advice, meal planning, food label analysis
  • Data Sent: Anonymized age groups, allergy and dietary information, food preferences, and meal photos (when you use the scanner or photo features)
  • Data NOT Sent: Your child's real name (replaced with "Child"), exact birth date, or email address
  • Photo Handling: Meal photos are sent as compressed images for analysis. Photos are processed in real-time and are not stored on Miriel or Google servers beyond the API request. Avoid including identifiable content (faces, personal items) in meal photos.
  • Privacy Policy: https://policies.google.com/privacy

USDA FoodData Central

  • Purpose: Nutritional database lookups for accurate food information
  • Data Sent: Food names and search queries only (no personal information)
  • Privacy Policy: https://www.usda.gov/privacy-policy

Open Food Facts

Backend Analytics (Supabase)

  • Purpose: Anonymous app usage analytics and customer support
  • Data Sent: Random device identifier, app usage events, app version, OS version, locale
  • Data NOT Sent: Names, email addresses, health data, or any child information
  • Control: You can disable analytics at any time in Privacy Settings

All third-party services are used solely to provide app functionality and are bound by their respective privacy policies.

4. Location Information

Miriel can optionally use your location to display real-world weather in the app experience.

  • How it works: Location is processed entirely on your device using Apple WeatherKit
  • What we access: Only your approximate location (city-level accuracy) for weather lookup
  • Data storage: Your location is never stored on our servers or sent to third parties
  • Control: You can deny location access anytime — the app will use seasonal weather patterns instead
  • Disabling: Go to iOS Settings > Privacy & Security > Location Services > Miriel to change permissions

Weather data enhances the experience but is completely optional. The app functions fully without location access.

5. Poseidon R&D Inc Data Processing

Miriel AI is developed and operated by Poseidon R&D Inc (mirielai.com).

Poseidon R&D Inc will process user data as described in this policy for the following purposes:

  • Service improvement and feature development
  • Debugging and error handling
  • Customer-generated support reports
  • Quality assurance and app optimization

All data processing follows the same privacy standards outlined in this policy. No data is shared with third parties beyond what is explicitly stated.

6. Data Storage & Security

  • Data is stored using Apple's secure SwiftData and syncs via iCloud when enabled
  • What syncs via iCloud: Child profiles, meal plans, nutrition logs, chat history, and app settings
  • What stays on-device only: Meal photos, cached data, and Keychain-stored credentials
  • iCloud data is encrypted by Apple both in transit and at rest
  • You can disable iCloud sync in iOS Settings > iCloud > Miriel
  • Sensitive data (passcodes) are encrypted using SHA-256 and stored in iOS Keychain
  • We use biometric authentication (Face ID/Touch ID) when available

7. Children's Privacy (COPPA)

Miriel is designed for parents to manage their children's nutrition. We are committed to protecting children's privacy:

  • We do not knowingly collect data from children under 13 without parental consent
  • Verifiable Parental Consent (VPC) is required before any data collection, implemented via email verification
  • Children's exact ages are never sent to AI services — only anonymized age groups (e.g., "Preschool", "Pre-Teen")
  • No third-party tracking or advertising is used
  • Parents have full control over their children's data
  • Parents can delete all child data at any time from Account settings
  • Parents can withdraw consent at any time, which will require re-verification to continue using the app

8. Your Rights

You have the right to:

  • Access: View all data we have about your children
  • Correct: Edit any incorrect information
  • Delete: Remove all data from Account > Delete All Data
  • Export: Download all your data in JSON or CSV format
  • Opt-out: Disable AI features or analytics from Privacy Settings
  • Withdraw Consent: Revoke parental consent at any time from Privacy Settings

9. Data Retention

  • Scan history: Retained until you delete it
  • Meal plans: Retained until you delete it
  • Anonymous analytics: Retained on our backend; deleted when you delete your account
